Unite Against Fascism states on its website that its aim is to deny the British National Party any chance of "gaining an electoral foothold"[3] stating that "there is a real danger that the BNP could get a significant platform in elected institutions." It claims the support of organisations representing labour, teachers, and rights activists.[12]

In November 2007, UAF organised a rally of over 1,000 people when BNP leader Nick Griffin and holocaust denier David Irving spoke at the Oxford Union.[13] On 9 June 2009, UAF demonstrated against a BNP press conference given by Griffin and Andrew Brons outside the Palace of Westminster following their election as MEPs. Demonstrators marched towards the group with placards, chanting anti-Nazi slogans, and threw eggs at Griffin, forcing the abandonment of the press conference. Members of the press were also hit. The protesters also kicked Griffin's car and beat it with placards as he was led away from the scene.[2] Two members of the public were hospitalised as a result of the demonstration.[14] Griffin claimed that the attack was carried out with the backing of the Labour Party.[15][16]

The following day, UAF demonstrated at the BNP's next attempt to hold a press conference at a pub in Miles Platting, North Manchester.[17] They chanted anti-fascist slogans and tried to drown out Griffin by playing Bob Marley songs at high volume. One protester was arrested after spitting in the direction of a car belonging to a BNP member.[17]

In January 2010, when the Pendle branch of the UAF removed a wreath from the War Memorial in Nelson that was laid down by Councillor Adam Grant, a former soldier and current British National Party member,[18] Richard MacSween of the Pendle UAF said, "The BNP have left a wreath and we have removed it because we don't approve of fascism." In response, Councillor George Adam, from the Nelson and District branch of the Royal British Legion, said: "I'm annoyed - they have no right to remove that wreath. The BNP is a legitimate political party and they have a right to lay down a wreath just as any other members of the public do." BNP Councillor Brian Parker added: "It's disgusting, and it's theft."[15][16]

On 19 August 2009, police arrested 19 protesters during a demonstration by UAF against the BNP's Red, White and Blue Festival in Codnor, Derbyshire.[19] Four people were charged, three with public order offences and one with unlawfully obstructing the highway.[20][21][22]

On 22 October 2009, the UAF demonstration against Nick Griffin's appearance on the BBC's Question Time programme resulted in injuries to three police officers.[23] UAF national officer and (then) SWP National Secretary Martin Smith was found guilty of assaulting one of the police officers at South Western Magistrates' Court, London, on 7 September 2010. He was sentenced to a 12-month community order, with 80 hours' unpaid work, and was fined £450 pending an appeal.[24][25]

On 20 March 2010, demonstrations from UAF and the English Defence League (EDL) in Bolton led to violent confrontations and the arrest of at least 55 UAF supporters, including the UAF protest organiser Weyman Bennett, on suspicion of conspiracy to commit violent disorder.[26][27][28] At least three EDL supporters were also arrested, and two UAF members were taken to hospital with a minor head and a minor ear injury.[26][27] After Bennett was charged and released, he accused the police of being hostile to anti-racists and called for an inquiry into the police's actions that day.[29] The police, while criticising the EDL for "vitriolic name-calling" blamed people predominantly associated with UAF for provoking violence and said that they "acted with, at times, extreme violence".[30] All charges against Weyman Bennett were eventually dropped. In response to this news he was quoted as saying: "This is a victory for anti-fascists and for the right to protest. I’m proud to say that the threat of these charges has not deterred any of us from continuing to stand up against the EDL. I can now continue my work without this serious false allegation hanging over me. It is imperative we continue to protest to protect our multi-racial communities."[31]

On 30 August 2010, violence occurred in Brighton, East Sussex, during a UAF protest against a march organised by a group called the English Nationalist Alliance. A spokesman for the police, who were attempting to keep 250 protesters and marchers apart, said, "Unfortunately a small group from the counter-demonstration [UAF] resisted this and threw missiles at the police." There were fourteen arrests during the violence.[32]

On 2 June 2013, 58 anti-fascist demonstrators were arrested by police under Section 14 of the Public Order Act[33] for failing to move up the street[34] away from a BNP demonstration outside the Houses of Parliament against what the BNP describe as Islamic "hate preachers".[35] Of the 58, only five were charged and their cases were dismissed at Westminster Magistrates' Court in April 2014.[36] The police had earlier banned the BNP from marching from Woolwich Barracks to the Houses of Parliament, fearing violence.[37]

In 2006 David Tate argued that the Socialist Workers Party was seeking to dominate the UAF.[38] David Toube claims that the organisations involved in the UAF avoid condemnation of antisemitism.[39]

LGBT rights activist Peter Tatchell has accused UAF of a selective approach to bigotry: "UAF commendably opposes the BNP and EDL but it is silent about Islamist fascists who promote anti-Semitism, homophobia, sexism and sectarian attacks on non-extremist Muslims. It is time the UAF campaigned against the Islamist far right as well as against the EDL and BNP far right."[25]

The journalist Andrew Gilligan has claimed that the UAF's reluctance to tackle Islamism is that several of its own members are supporters of such extremism. The UAF's vice-chairman, Azad Ali, has links to al-Qaeda and is also community affairs coordinator of the Islamic Forum of Europe, which Gilligan describes as "a Muslim supremacist group dedicated to changing 'the very infrastructure of society, its institutions, its culture, its political order and its creed from ignorance to Islam'".[25] According to Gilligan, Michael Adebolajo, one of the murderers of Lee Rigby in 2013, spoke "on the margins" of a 2009 UAF demonstration in Harrow.[25] Secretary Weyman Bennett responded by saying that Adebolajo was not an official speaker.[25]
